Change Mouse scrolling in Excel from L to R to Up & Down
 

I have an excel worksheet that we use daily. The scoll button on the mouse
will only scroll left and right.... It will not scroll up and down. If I
open a new worksheet it works fine (up & down) until I copy over the data
from my active worksheet then it scrolls Left and Right again. Could this
have something to do with the text wrap feature being turned on in a couple
of the columns? Is there any way to correct this without recreating the
entire project from scratch?
